Marty just released Blindfold Slide Puzzle.
It's a fully accessible sliding tile puzzle game.

The slide puzzle (also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and many others) is a puzzle that consists of a grid of numbered
square tiles in random order with one tile missing. The common puzzle is known as the 15 puzzle, with 4 rows and 4 columns, filled with tiles numbered

on how to play and win.
